Sirefef virus issue

Hello, my desktop seemed to have caught the sirefef virus, windows security essential is forcing the desktop to restart after one minute even though it claimed to have clean the virus. I go into safemode to try to run Malwarebytes but the desktop shuts down before the scan can finish. I notice this is a common problem from the topic threads but it seems recommended that I make my own thread topic other than copying other users. I am running Windows 7 64-bit home premium if that helps.

Download attached fixlist.txt file and save it to the very same USB flash drive you've been using. Plug the drive back in.

NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

On Vista or Windows 7: Now please enter System Recovery Options.
On Windows XP: Now please boot into the UBCD.
Run FRST64 and press the Fix button just once and wait.
The tool will make a log on the flashdrive (Fixlog.txt) please post it to your reply.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**

Never rename Combofix unless instructed.

Close any open browsers.

Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".

Click onthis linkto see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

Close any open browsers.

WARNING: Combofix will disconnect your machine from the Internet as soon as it starts

Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.

If there is no internet connection after running Combofix, then restart your computer to restore back your connection.

Double click on combofix.exe & follow the prompts.

NOTE1. If Combofix asks you to install Recovery Console, please allow it.NOTE 2. If Combofix asks you to update the program, always do so.

When finished, it will produce a report for you.

Please post the "C:\ComboFix.txt"

**Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall
**Note 2for AVG and CA Internet Security (Total Defense Internet Security) users: ComboFix will not run until AVG/CA Internet Security is uninstalled as a protective measure against the anti-virus. This is because AVG/CA Internet Security "falsely" detects ComboFix (or its embedded files) as a threat and may remove them resulting in the tool not working correctly which in turn can cause "unpredictable results". Since AVG/CA Internet Security cannot be effectively disabled before running ComboFix, the author recommends you to uninstall AVG/CA Internet Security first.
Use AppRemover to uninstall it: http://www.appremover.com/
We can reinstall it when we're done with CF.
**Note 3: If you receive an error "Illegal operation attempted on a registery key that has been marked for deletion", restart computer to fix the issue.
**Note 4: Some infections may take some significant time to be cured. As long as your computer clock is running Combofix is still working. Be patient.

Make sure, you re-enable your security programs, when you're done with Combofix.

NOTE.If, for some reason, Combofix refuses to run, try one of the following:

1. Run Combofix from Safe Mode.

2. Delete Combofix file, download fresh one, but rename combofix.exe to your_name.exe BEFORE saving it to your desktop.
Do NOT run it yet.
Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.
There are 4 different versions. If one of them won't run then download and try to run the other one.Vista and Win7 users need to right click Rkill and choose Run as Administrator
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.
